CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Patent Application No. PCT/EP2022/066884, filed Jun. 21, 2022, which claims priority to European Patent Application No. 21180708.6, filed Jun. 21, 2021, the disclosures of which are incorporated by reference herein.

TECHNICAL FIELD

The present invention relates to salts of N-{3-[1-(2-nitrophenyl)-1H-pyrrol-2-yl]-allylidene}-aminoguanidine having a high solubility at low pH.

BACKGROUND

The melanocortin system is a set of neuropeptidergic and immuneendocrine signalling pathways that play an integral role in the homeostatic control of a diverse array of physiological functions, including melanogenesis, stress response, inflammation, immunomodulation and adrenocortical steroidogenesis. It consists of multiple components, including the five G protein-couple melanocortin receptors: melanocortin receptor 1 (MC1R) to MC5R; peptide ligands; α, β, γ-melanocyte stimulating hormone (α, β, γ-MSH); adrenocorticotropic hormone (ACTH) secreted by the anterior pituitary; and endogenous antagonists. The biological functions of the melanocortin system are mediated by the five melanocortin receptors (MCRs), which have distinct tissue distribution, convey different signalling and exert varying biological activities in different organ systems.

Phenyl pyrrole aminoguanidine derivatives with activity on the melanocortin receptors have previously been disclosed. One example of such compound is the anti-inflammatory AP1189 (N-{3-[1-(2-nitrophenyl)-1H-pyrrol-2-yl]-allylidene}-aminoguanidine) which was first shown to bind the MC1R and later was identified as a biased dual agonist at receptors MC1R and MC3R that does not provoke canonical cAMP generation (and hence no MC1R-induced melanogenesis) but instead appear to induce alternative pathways including ERK1/2-phosphorylation and Ca²⁺ mobilisation.

SUMMARY

DETAILED DESCRIPTION Definitions

By a “compound of formula I”, “compound I”, and “AP1189” is meant the compound N-{3-[1-(2-nitrophenyl)-1H-pyrrol-2-yl]-allylidene}-aminoguanidine, which has the chemical structure of formula I:

as well as tautomers and stereoisomers thereof. Another name for the compound is N″-[(E)-[(2E)-3-[1-(2-nitrophenyl)-1H-pyrrol-2-yl]prop-2-en-1-ylidene]amino]guanidine.

In some instances the term “AP1189” may refer to either the free base structure of Formula I or it may refer to the acetate salt of AP1189. Preferable, the term “AP1189 free base” refers to the structure of Formula I. Preferably, the term “AP1189 acetate” refers to the acetate salt of the structure of Formula I.

As used herein, the term “SP1189” refers to the succinate salt of the structure of Formula I. The terms “SP1189” and “AP1189 succinate” are synonymous as used herein.

Regarding the naming of salts, it is to be construed that terms such as “N-{3-[1-(2-nitrophenyl)-1H-pyrrol-2-yl]-allylidene}-aminoguanidine acetate” and N-{3-[1-(2-nitrophenyl)-1H-pyrrol-2-yl]-allylidene}-aminoguanidinium acetate” are synonymous, i.e. when an anion is written immediately after “N-{3-[1-(2-nitrophenyl)-1H-pyrrol-2-yl]-allylidene}-aminoguanidine”, then the protonated form of “N-{3-[1-(2-nitrophenyl)-1H-pyrrol-2-yl]-allylidene}-aminoguanidine” is meant, i.e. “N-{3-[1-(2-nitrophenyl)-1H-pyrrol-2-yl]-allylidene}-aminoguanidinium”.

Heated at 50-55° C. for 1 hour before additional 0.11 equivalent acetic acid was added and the mixture was heated to reflux for at least 2 hours. The suspension was cooled to 60° C. before tert-butyl methyl ether was added. Cooled and kept at 2-5° C. for 10-16 hours. Filtered and washed with tert-butyl methyl ether, before recrystallized from ethanol.

The procedure produces a polymorph of AP1189 acetate salt corresponding to XRPD pattern 1.

Exemplary Procedure for Formation of Succinate Salt of AP1189

2-propanol:water 90:10 v/v was added to AP1189 acetate to prepare a slurry. 2-propanol:water 90:10 v/v was added to 1.1 equivalents of succinic acid. The counterion slurry was added to the acetate salt slurry. Temperature cycling was carried out between ambient and 40° C. for ca. 18 h with 4 hour hold periods at ambient temperature and 4 hour hold periods at 40° C. The entire slurry was then isolated by Buchner filtration and washed with deionised water. The solids were dried under vacuum at ambient.

The procedure produced a polymorph of AP1189 succinate salt corresponding to XRPD pattern 1.

Salt Break of Freebase AP1189

Ethyl acetate and 1 M sodium bicarbonate was added to AP1190 acetate to create a biphasic mixture. The mixture was transferred to a separating funnel and the aqueous phase was removed. The organic phase was washed with water. The organic phase was dried with sodium sulphate. The solvent of the organic phase was removed by rotary evaporation.

The procedure produced AP1189 freebase as a solid.

Example 2: Polymorphism Assessment for AP1189 Acetate Salt

Methods

A polymorphism assessment was carried out in order to identify alternate polymorphs of AP1189 acetate: AP1189 acetate was dissolved in 1,4-dioxane-water and lyophilized to obtain an amorphous solid. Aliquots were suspended in the specific solvents and heated in temperature cycles between ambient and 40° C. for 3 days, before being isolated by filtration.

Results

Table 2 outlines the results of the polymorphism study. Acetate Pattern 1 was obtained from 8 solvent systems. A mixture of Pattern 1 and 2 was obtained from 8 solvent systems. Pattern 3 was obtained from THF. Extended temperature cycling for a further 3 days for the acetate Pattern 1 and 2 mixture from ethyl acetate resulted in conversion to acetate Pattern 1.

Conclusion

The polymorphism study for AP1189 acetate revealed three different polymorphs, corresponding to XRPD Pattern 1, Pattern 1 and 2 (i.e. Pattern 2 as a mixture with Pattern 1), and Pattern 3.

Example 3: X-Ray Powder Diffraction

Methods

XRPD analysis was carried out on a PANalytical X'pert pro with PIXcel detector (128 channels), scanning the samples between 3 and 35° 2θ. The material was gently ground (where required) to release any agglomerates and loaded onto a multi-well plate with Kapton or Mylar polymer film to support the sample. The multi-well plate was then placed into the diffractometer and analysed using Cu K radiation (α1 λ=1.54060 Å; α2=1.54443 Å; p=1.39225 Å; α1:α2 ratio=0.5) running in transmission mode (step size 0.0130° 2θ, step time 18.87 s) using 40 kV/40 mA generator settings.

Conclusion

X-Ray Powder Diffraction Data was Collected for a Selection of Different AP1189 Salts.

Example 4: Thermogravimetric Analysis/Differential Scanning Calorimetry and Differential Scanning Calorimetry

Methods

For the TGA/DSC assessment, approximately, 5-10 mg of material was added into a pre-tared open aluminium pan, loaded into a TA Instruments Discovery SDT 650 Auto-Simultaneous DSC and held at room temperature. The sample was then heated at a rate of 10° C./min from 30° C. to 400° C. during which time the change in sample weight was recorded along with the heat flow response (DSC). Nitrogen was used as the sample purge gas, at a flow rate of 200 cm³/min.

For the DSC assessment, approximately, 1-5 mg of material was weighed into an aluminium DSC pan and sealed non-hermetically with an aluminium lid. The sample pan was then loaded into a TA Instruments Discovery DSC 2500 differential scanning calorimeter equipped with a RC90 cooler. The sample and reference were heated to 230° C. or 240° C. at a scan rate of 10° C./min and the resulting heat flow response monitored. The sample was re-cooled to 20° C. and then reheated again to 230° C. or 240° C. all at 10° C./min. Nitrogen was used as the purge gas, at a flow rate of 50 cm³/min.

Example 6: Solubility of AP1189 and its Salts

Methods

The solubility of AP1189 acetate (XRPD pattern 1), fumarate (XRPD pattern1), and succinate (XRDP pattern 1) salts were assessed in 0.5 M buffer solutions having pH of 1.2 and 4.5.

Results

The results of the study are shown in tables 38a and 38b for 0.5 M and 0.2 M buffers, respectively. Table 38c shows the solubility of further AP1189 salts.

For the 0.5 M buffers, the highest solubility was observed for acetate Pattern 1. Higher solubility was observed for succinate Pattern 1 compared with fumarate Pattern 1. XRPD analysis showed acetate Pattern 1 remained at pH 4.5. At pH 1.2 for the acetate, a likely HCl salt (assigned as HCl Pattern 1) was formed. Succinic acid was obtained from the succinate Pattern 1 experiment at pH 1.2. The free succinic acid in the residual solids may indicate that the system was not saturated with respect to the API and the solubility may be higher than that reported.

Conclusion

The test compounds exhibited remarkably different solubilities, especially at low pH. Specifically, the acetate and succinate salts showed high solubility at pH 1.2, indicating the potential for using these compounds in applications where a high solubility at low pH is desirable.

Example 7: Polymorph Study of AP1189 Succinate

Materials and Methods

Approximately 300 mg of the received succinate salt was added to 14 mL vials. The required volume of the appropriate solvent system was added to each vial, and the experiments were stirred at 70-73° C. until complete dissolution was achieved. The experiments were then cooled to 68° C., and seeded with AP1189 succinate. 5 to 15% seed load was used. The experiments were stirred at 68° C. for another 1 h to allow for equilibration. The experiments were then cooled to 5° C. at 0.1° C./min, and stirred at 5° C. until isolation. The experiments (slurries) were vacuum filtered, and the cakes were each washed with 3 mL of the respective input solvent system (precooled at 5° C.). The solids were analysed by XRPD to check the polymorphic form. The remainder of the solids were druid under vacuum at ambient for ca. 3 days. The dried solids were characterised. The concentrations of the recovered mother liquors and was were determined by HPLC.

Results

Both damp and dried crystallised solids were consistent with Pattern 1 of the succinate salt. Table 39 summarises the findings of the study.

The experiments were then cooled to 5° C. at 0.1° C./min, and stirred at 5° C. After ca. 18 h of stirring at 5° C., 200 μL aliquot of each slurry was extracted and centrifuged using 0.2 μm nylon tubes. The isolated solids were dried under vacuum at ambient and analysed by HPLC (purity). The concentration and purity of the mother liquors were also determined by HPLC. To the remainder of the experiments, anti-solvent addition was carried out at 5° C., to reach the target final ratio. Afterwards, stirring continued at 5° C. for another ca. 4 h. The experiments (slurries) were vacuum filtered and the cakes each washed with 0.9 mL of the respective organic solvent (pre-cooled at 5° C.). The solids were dried under vacuum at ambient for ca. 48 h. The dried solids were characterised. The mother liquors were subsampled and analysed by HPLC for concentration and solution purity determination. The rest of the mother liquors were left open in an oven, to allow the solvents to evaporate under vacuum, at ambient. After 3 days, the residual solids were analysed by XRPD and HPLC (purity).

Results

All isolated solids were consistent with Pattern 1 of the succinate salt. Table 40 summarises the findings of the study.

Materials and Methods

Approximately 5 g of AP1189 succinate was added to temperature controlled reactor in an EasyMax 102 (100 mL vessel). 55.6 mL (11.1 vol.) of 1-propanol/water (50:50 v/v %) was added to the reactor, and the experiment was stirred at 70° C. Target concentration was 90 mg/mL. Stirring speed was 200 rpm. When complete dissolution was observed, the experiment was cooled to 55° C., and seeded with AP1189 succinate. 2% seed load was used, and it persisted with evidence of slurry formation. Post-seeding, stirring continued at 55° C. for 2 hours to allow experiment to equilibrate. The experiment was cooled to 5° C. at 0.1° C./min, and allowed to stir at 5° C. for 1 h. Stirring speed was increased to 300 rpm during the cooling step. At 5° C., water (pH 7.22) was added to the experiment as an anti-solvent at 1 vol./hr, to reach a target ratio of 40:60% v/v. 14 mL (2.8 vol.) of water was added. Post-addition, stirring continued at 5° C. for ca. 6 hours. A subsample of the slurry was extracted into a 0.2 μm nylon tube and centrifuged. The concentration and solution purity of the isolated mother liquor were determined by HPLC. The isolated solid was dried under vacuum at ambient for ca. 4 days, and analysed by HPLC for purity analysis. At 5° C., more water was added as anti-solvent at 1 vol./hr, to reach a target ratio of 30:70% v/v. 23.4 mL (4.6 vol.) of water was added. Stirring speed was increased further to 350 rpm during the addition. Post-addition, stirring continued at 5° C. for another 90 min. At 5° C., the slurry was vacuum-filtered using Buchner funnel. The filter cake was washed with 10 mL (2 vol.) of water (precooled to 5° C.) and dried under vacuum at ambient for ca. 4 days. XRPD analysis was carried out on both the damp and dried solid sample.

Materials and Methods

3.4 g of AP1189 succinate and 2.9 g of AP1189 acetate were added to separate vials containing 10.0 mL of buffer solution pH 1.2 (one determination per salt). For the AP1189 acetate and AP1189 succinate solutions, the pH was measured to 3.9 and 2.2 respectively. As a result, the pH was adjusted to 1.2 with concentrated hydrochloric acid in both solutions. Both sample preparations were diluted 500 times with the sample diluent (acetonitrile:water 1:1 v/v).

The diluted samples preparations were analysed by HPLC within 5 hours from preparation and the content of AP1189 was determined from the area under the curve by comparing to standard solutions of AP1189 acetate and AP1189 succinate respectively.

Equilibrium solubilities were also assessed at pH 4.5 and pH 6.8 following the procedure as described in WHO Technical Report Series 1019, 2019 annex 4: Protocol to conduct equilibrium solubility experiments for the purpose of Biopharmaceutics Classification System-based classification of active pharmaceutical ingredients for biowaiver.
